Abstract

A flat prefabricated panel formed from a three-dimensional metal screen (1) and from a reference layer of foamed plastic (2) is converted into a curved panel suitable for the formation of a curved wall by cutting said screen along parallel lines (7) on one face of the panel, utilizing said cut line (7) to incurvate the panel to make the opposite face thereof concave and finally restoring the integrity of the screen on said face of the panel by means of reticular connecting strips (8) applied along said cutting lines (7).
